[PATCH 0/6] of, of_gpio, of_spi: Fix and improve of_parse_phandle_with_args, of_gpio_named_count and of_spi_register_master

[Andreas Larsson]

This patch series fixes a bug where of_gpio_named count relied upon a return
value that was no longer returned from of_parse_phandle_with_args and adds the
possibility for of_gpio_named_count to return error values.

In addition, for of_spi_register_master it fixes a bug, adds documentation,
adds fetching of gpio flags and initializes gpio values to be consistent with
return values from of_parse_phandle_with_args.

Tested on sparc. Build tested on x86, arm and ppc.

Andreas Larsson (6):
  of: Return -EEXIST from of_parse_phandle_with_args for holes in
    phandle list
  of: Return -ENXIO from of_parse_phandle_with_args for too large index
    and return errors from of_gpio_named_count
  of_spi: Initialize cs_gpios properly
  of_spi: Document cs_gpios and cs_gpio in kernel-doc
  of_spi: Add fetching of of_gpio flags to of_spi_register_master
  of_spi: Initialize cs_gpios and cs_gpio with -EEXIST
